XPS Insulation Boards - Living Heat

Underfloor Heating Insulation

Living Heat XPS Insulation boards can be stuck down with the same flexible tile adhesive being used to complete your tiling. We would recommend that you use the 10mm thick insulation boards. However, if you do have any height restrictions, as a result the 6mm hard insulation boards will deflect most of your heat upwards. Increasing both the efficiency and the response rate of your underfloor heating system.

Our hard insulation boards measure 620 x 600mm or 600 x 600mm for 20mm boards, making them super easy to handle. And they have been specially designed for use with our underfloor heating systems. The insulation boards provide a high thermal barrier between the sub-floor and also the final floor covering. For example with tiles. This greatly increases the efficiency of the system and reduces any heat loss. Available in 6, 10 and 20mm depths these insulation boards are designed for use under tile and stone floors, and can also be used under wooden or laminate floors.
